Alternatively, the 2-hole flanged panel mount connector will fit the same 21mm hole while allowing the use of 2 fasteners to ensure the connector does not twist or loosen.

The SY21 connectors have a choice of solder, crimp or screw terminals giving you a variety of easy termination styles with all the contacts in the SY21 range being gold plated for better conductivity. The cable mount connectors are available with two cable size diameters these being 4.5-7mm or 7-12mm allowing for a selection of cables to be mated.

With its larger body size ideal for tougher environments and quick-connect bayonet mating, the SY21 connectors are ideal for power or data applications including Outdoor Lighting, Outdoor Security Cameras, Off-Road Vehicles and Industrial Control Systems.
